Re: Husband is overweight- it's hurting me to have sex!
I agree with stargatefan on this one. Have the talk with him. Stating that he is your man but at the current weight you both are at, you won't have a long life together. That you're afraid of the health of both of you. Before you talk to him, research and price gym memberships for the both of you. If you talk to him about going to the gym, then go!!! Find a trainer there that will work with the both of you.
If you do the shopping, start buying all low fat or no fat products. Start buying a lot more fruits and veggies. Start planning a health menu throughout the week. If there's nothing else in the house, then that's what he'll eat.
Don't make it about sex, make it about your health. To be honest, you start to live a healthy lifestyle, the sex will correct on it's own (actually, it will get a lot better) so there's no reason to bring it up.
